Question

area of triangle 87 CM square. Base = 15 cm
Height= ?

Answer 1

area of triangle is equal to
1/2 × base ×height
therefore
87=1/2 × 15 × H
H= 11.6

Answer 2

Given,
Area of triangle = 87 cm^2.
Base = 15 cm.

We know that,
Area of triangle = 1/2 ( Base * Height)

=> 87= 1/2*15*height

=> 174 = 15*height

=> height =174/15

=> Height =11.6 cm.

Therefore, Height of the triangle is 11.6 cm.
