Geometry

Area of a Rectangle: A = lw

• l is length
• w is width

Explanation:

Step 1: Define

A = 1650 yd²

l = 55 yd

w = unknown

Step 2: Solve for w

1. Substitute in variables [Area of a Rectangle]: 1650 yd² = (55 yd)(w yd)
2. [Division Property of Equality] Divide 55 yd on both sides: 30 yd = w
3. Rewrite: w = 30 yd
