Question

find the base if the triangle with area 54cm and height of 9 cm

Answer 1

the ans is 12 cm I hope it will help u

Answer 2

Ello There!

-----------------

Given,

Area of Δgle = 54cm²

Height = 9cm

To Find

Base of the triangle.

Solution

We know that,

Area of a Δgle = $\frac{1}{2}$ b × h

We use this formula to find out the base of this triangle.

Area of a Δgle = $\frac{1}{2}$ b × h

54 = $\frac{1}{2}$ b × 9

Now, we take $\frac{1}{2}$ to the other side of the equal symbol.

54 × 2 = 9b

   108 = 9b

$\frac{108}{9}$ = b

     12 = b    

  b = 12cm
