Question

This du today I NEED HELP!!!!! IS URGENT!!!!!!!!!!!!!

Answer 1

x = 8

Explanation:

The perimeter of a body is the sum of all its sides.

Perimeter of the triangle;

hypothenuse + opposite + adjacent = x+6 + x + 3 + x + 9 = 3x + 18

Perimeter of the rectangle = x+1 + x + 4 + x + 1 + x + 4 = 4x + 10

Now,

Since their perimeter is equal;

3x + 18 = 4x + 10

3x - 4x = 10 - 18

-x = -8

x = 8
