Question

The perimeter of triangle is 30 units. What will the perimeter of rectangle be (in same units) ?

PLS ANSWER ASAP !!

Answer 1

Let x=width (w).

Then 2x would be length (l).

Since P=2l+2w, we can substitute our values in.

30=2(2x) + 2x. Now simplify and solve.

30=4x+2x

30=6x

5=x

So the width is 5, and the length is twice that. So l=10.

Now you can find the area.

A=lw

A=5*10

A=50 square cm
