| Let’s find the length of the rectangle:
5/17 * 102 = 30 cm.
Let’s find the width of the rectangle. Let’s take the width of the rectangle as “x”. The perimeter of the rectangle is the sum of the lengths of the sides. Let’s make an equation and solve it:
2 * (x + 30) = 102
x + 30 = 51
x = 51 – 30
x = 21 cm.
Find the area of the rectangle by multiplying the length by the width:
30 * 21 = 630 cm2
Answer: The area of the rectangle is 630 cm2.
