I don’t understand this question either sorry
answer:
area: 40cm²
perimeter = 26cm
step-by-step explanation:
- i do not know which one this is telling you to find so i put both area and perimeter
area:
- know the formula
- formula = l x w
- l = length
- w = width
- plug in what you have
l x w
5 x 8
= 40cm²
perimeter:
- for this you just have to each side
- since this is rectangle opposite sides are equal
5 + 5 + 8 + 8
= 26cm
