This paper reports on a study of Year 7 students' understanding of area measurentent. 43 students completed a written test just before and immediately afrer study'ing areas oJ rectangles and triangles. Twelve of these students, representing the range of ability in the sample, were interviewed as...
of it . it is applicable to all types of triangles , whether it is scalene, isosceles or equilateral. to be noted, the base and height of the triangle are perpendicular to each other. the unit of area is measured in square units (m 2 , cm 2 ). example: what is the area of a ...

Class 8 MATHS Triangles ABC and DEF are similar. If th... Triangles ABC and DEF are similar. If the length of the perpendicular AP from A on the opposite side BC is 2 cm and the length of the perpendicular DQ from D on the opposite side EF is 1 cm, then what is the area of ...
Triangles A B C and D E F are similar. If area ( A B C)=16\ c m^2 , area ( D E F)=25\ c m^2 and B C=2. 3 c m , find E Fdot (ii) If area ( A B C)=9\ c m
length = area/width why area of the rectangle is length x breadth? the diagonals of the rectangle divide it into two equivalent right-angled triangles. therefore, the area of the rectangle will be equal to the sum of the area of these two triangles. suppose, abcd is a rectangle. now...
Therefore, the overlapping area can be calculated by summing the areas of the triangles formed by the three different intersections and the areas of the three segments. Finally, Type C is characterized by only two unique intersections, where each chord spans two segments in both directions, as ...

The product of the area of two triangles formed by one diagonal is equal to the product of the area of two triangles formed by the other diagonal. The median of a trapezoid is parallel to both bases. If both pairs of opposite sides of a trapezoid are parallel, it is referred to as a...
