Step-by-step explanation:

Alright, lets get started.

Area is given as 49 square inches.

The formula for area A =  

base is given as x

Height is given as x

Hence area is A

A =  

Multiplying 2 in both sides

Taking square root on both sides

hence the answer is x = 9.9 in   :  Answer

Hope it will help :)

The value of x is 9.9 in.

Solution:

The given image is a triangle.

Base of the triangle = x

Height of the triangle = x

Area of the triangle = 49 sq. in

To find the value of x:

Area of the triangle =  

Substitute the given values in the formula.

Multiply by 2 on both sides, we get

Taking square root on both sides, we get

⇒ x = 9.9 in

Hence the value of x is 9.9 in.
