4. a rectangle has a width of 2 cm and a perimeter of 25 cm. find the length and the area.
a ) ℓ = 12.5 cm and a = 21 cm2
b) ℓ = 10.5 cm and a = 25 cm2
c) ℓ = 10.5 cm and a = 21 cm2
d) ℓ = 12.5 cm and a = 25 cm2

l = 10.5 cm and A = 21 cm2

Step-by-step explanation:

Area is w*l

Perimeter is 2(w+l)

Replacing the information known in the problem you can get the length with the perimeter

P = 2(w+l)

25 = 2(2+l)

12.5 = 2 + l

10.5 cm = l

with the length now you can find the area

A = w*l

A = 2*10.5

A = 21 cm2

15% chance.
