The perimeter of a rectangle is 42 cm and the area is 80 cm². Write an equation to model the situation and find the dimensions of the rectangle. ​

16cm by 5cm

Step-by-step explanation:

P=2(l+w)  

A= wl

80 factorization: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80.

you then would have to find 2 numbers that would add up to make 42.

When you try 16*2+5*2= 32+10= 42 cm as your perimeter.

16*5= 80 cm^2 as your area.

the answer is 0.3175 hope that you ^w^
