Question

the area of a triangle is equal to that of a square whose each side measure 35 cm find the side of the triangle whose corresponding altitude is 28cm

Answer 1

side of square is 35
area =1225
area of triangle =1/2×base×height

Answer 2

Side of square= 35 cm

altitude of triangle= 28 cm

Area of square= a²

=35*35

= 1225 cm²

Area of triangle= 1/2 × base× height

1225=1/2×base×28

(1225×2)/28= base

base=  2450/28

base= 87.5 or 86 cm²
