PREP Algebra Unit 1 Day 3 Homework

Front

What is the formula for the perimeter of a rectangle?

Back

Perimeter = 2(length + width)

Front

How do you calculate the area of a rectangle?

Back

Area = length × width

Front

What is the perimeter of a rectangle with length 20 mm and width 10 mm?

Back

Perimeter = 2(20 mm + 10 mm) = 60 mm

Front

If a rectangle has an area of 60 cm² and a length of 15 cm, what is its width?

Back

Width = Area / Length = 60 cm² / 15 cm = 4 cm

Front

What is the area of a rectangle with length 8 cm and width 5 cm?

Back

Area = 8 cm × 5 cm = 40 cm²

Front

What is the area of a rectangle with dimensions 9 units by 4 units?

Back

Area = 9 units × 4 units = 36 square units

Front

How do you find the area of a composite figure?

Back

Divide the figure into simpler shapes, calculate the area of each, and then sum them up.

Front

What is the area of a rectangle with a length of 12 cm and a width of 2 cm?

Back

Area = 12 cm × 2 cm = 24 cm²

Front

If the perimeter of a rectangle is 82 mm and the length is 30 mm, what is the width?

Back

Width = (Perimeter / 2) - Length = (82 mm / 2) - 30 mm = 11 mm

Front

What is the area of a rectangle with a length of 10 cm and a width of 6 cm?

Back

Area = 10 cm × 6 cm = 60 cm²
