Answer:

P = 37 cm

A = 85 cm^2

Explanation:

l = length, w = width, A = Area, P = Perimeter

l = 10 cm

w = 8.5 cm

A = l * w

P = 2l + 2w

Solve for Area:

A = 10 cm* 8.5 cm ==> substitute l = 10 cm and w = 8.5 cm

A = 10 * 8.5 * cm * cm ==> combine like terms

A = 85 cm^2

Solve for Perimeter:
P = 2(10 cm) + 2(8.5 cm) ==> substitute l = 10 cm and w = 8.5 cm

P = 20 cm + 17 cm ==> simplify

P = 37 cm
