Question

A= 49 sq. in.

Find the value of x. If necessary, round to the nearest tenth.

Answer 1

A=1/2bh :area of a triangle
because the base and height are both x you must multiply x•x = x square

49= 1/2x^2
98= x^2
x= 9.9

Answer 2

9.90 inches

Explanation:

Area of a triangle is equal to base times height divided by 2.

`bh/2`

Base and height is x.

`xx/2=49`

Solve for x.

`x^2=49 * 2`

`x^2=98`

`x=√(98)`

`x=9.899495`
