Question

Find the value of x. if necessary, round to the nearest tenth a=47sq in

Answer 1

The answer is 9.7 in

..................................

Answer 2

the picture in the attached figure

we know that

area of the triangle is equal to

`A=(b*h)/2`

in this problem

A=47 in²

b=x

h=x

so

`47=x*x/2 \\ x^(2) =94 \\ x= √(94) \\ x=9.69 in \\ x=9.7in`

therefore

the answer is

x=9.7 in
