Find the perimeter of the rectangle and the area of the rectangle?? Show all your work please

Perimeter: 8x+8

Area: 16x+16

Step-by-step explanation:

Combine only like terms

(4x+2) + (4x+2) +2+2= 8x+8

(4x+2) x (4x+2) x 2 x 2= 16x+16

step-by-step explanation:

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
