Area and Surface Area

Front

What is the formula for finding the area of a rectangle?

Back

Area = length × width

Front

What is the formula for finding the surface area of a rectangular prism?

Back

Surface Area = 2(lw + lh + wh) where l = length, w = width, h = height

Front

If a rectangle has a length of 10 cm and a width of 5 cm, what is its area?

Back

Area = 10 cm × 5 cm = 50 cm²

Front

What is the difference between area and surface area?

Back

Area measures the space inside a 2D shape, while surface area measures the total area of the surface of a 3D object.

Front

How do you find the area of a triangle?

Back

Area = 1/2 × base × height

Front

What is the area of a square with a side length of 4 cm?

Back

Area = 4 cm × 4 cm = 16 cm²

Front

If the area of a rectangle is 60 cm² and the width is 6 cm, what is the length?

Back

Length = Area ÷ Width = 60 cm² ÷ 6 cm = 10 cm

Front

What is the surface area of a cube with a side length of 3 cm?

Back

Surface Area = 6 × (side length)² = 6 × (3 cm)² = 54 cm²

Front

How do you calculate the area of a circle?

Back

Area = π × (radius)²

Front

What is the surface area of a cylinder with a radius of 2 cm and a height of 5 cm?

Back

Surface Area = 2πr(h + r) = 2π(2 cm)(5 cm + 2 cm) = 28π cm²
