Find the value of x so that the figures have the same perimeter. (MARKING AS BRAINS ST FOR PERSON WHO. GIVES THE ANSWER)

10) So here, in the first figure –

We are given a Rectangle and we know formula for perimeter of a rectangle's given

In case of 2nd figure a tiangle's given whose formula of Perimeter will be

According to the question :-

↠Perimeter of rectangle = Perimeter of triangle

↠ x+3 +x+5+x+4 = 2 (x+4+x-2)

↠ 3x + 12 = 2(2x+2)

↠ 2(2x+2) = 3x + 12

↠ 4x +4 = 3x+12

↠ 4x-3x +4-12 = 0

↠ x -8 =0

↠ x = 8

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
