Excellence:
A rectangle has a perimeter of 52cm. The length of the rectangle is 4b and the width of the rectangle is b + 6. Find the value of b
4b + 4b + b + 6 + b + 6 = 52
10b + 12 = 52
10b = 40
b = 4cm
Excellence:
A square has a perimeter of 48mm. The length of a side is 2y + 4. Find y
2y + 4 + 2y + 4 + 2y + 4 + 2y + 4 = 48
8y + 16 = 48
8y = 32
y = 4mm
