Question

A and B are two similar 2D shapes.
B
15 cm
А
12 cm
The area of shape A is 200 cm”.
Calculate the area of shape B.​

Answer 1

Solution :-

since we have given that both A and B are similar shapes .

so,

→ Ratio of areas of these two shapes = Ratio of square of their heights .

then,

→ Area of A / Area of B = (Height of A)²/(Height of B)²

putting values ,

→ 200/Area of B = (12)²/(15)²

→ 200 / Area of B = 144/225

→ Area of B = (225 * 200)/144

→ Area of B = 312.5 cm² (Ans.)
