Answer:
See explanation
Step-by-step explanation:
We have the length of the rectangle as 2w - 6 and width of the rectangle as w. The perimeter of a rectangle is given by 2(l + b) hence;
perimeter of the rectangle = 2 (2w - 6 + w) = 6w -12
For an equilateral triangle in which each side is w + 8, its perimeter is;
3(w + 8) = 3w + 24
Then the question goes further to say that the perimeter of the rectangle and equilateral triangle are equal
6w -12 = 3w + 24
6w - 3w = 24 + 12
3w = 36
w =12
Hence perimeter of rectangle = 6(12) -12 = 60
Perimeter of equilateral triangle =3(12) + 24 = 60
Answer:
Which expression represents the rectangle’s perimeter?
✔ 2(2w – 6 ) + 2(w)
Which expression represents the triangle’s perimeter?
✔ 3(w + 8)
What is the perimeter of both polygons?
✔ 60 units
