Question

The shape of the top surface of a table is a trapezium. Find its area if its parallel sides are 1 m and 1.1 m and perpendicular distance between them is 0.7 m.

Answer 1

Answer:

A = 0.735 m²

Step-by-step explanation:

A = $\frac{a + b}{2}$h

A = $\frac{1 + 1.1}{2}$ * h

A = 1.05 m * 0.7 m

A = 0.735 m²

Hope this helps you.

Answer 2

Given,

• The shape of the top surface of a table is a Trapezium.
• The Parallel Sides are 1m & 1.1m
• The Height = 0.7m

To Find,

• The Area of given Trapezium.

Solution,

A = 1m •••(Given)

[1m = 100cm]

→ A = 1m

→ A = 1 × 100m

→ A = 100m

B = 1.1m •••(Given)

[1m = 100cm]

→ B = 1.1m

→ B = 1.1 × 100cm

→ B = 110cm

H = 0.7m •••(Given)

[1m = 100cm]

→ H = 0.7m

→ H = 0.7 × 100cm

→ H = 70cm

Area of Trapezium

Area of Trapezium = ½ × (Sum of Parallel Sides) × Height

→ Area of Trapezium

= ½ × (A + B) × H

→ Area of Trapezium

= ½ × (100cm + 110cm) × 70cm

→ Area of Trapezium = 210cm × 35cm

→ Area of Trapezium = 7350cm²

Required Answer

The Area of Trapezium = 7350 square cm
