Question

find the area in square meters of triangle whose base and altitude are as under base = 10.5cm altitude = 6 cm


base =1.5 m altitude =0.8 m​

Answer 1

Answer:

Formula for area of a triangle =

Formula for area of a triangle =\frac{1}{2} \times b \times h21×b×h

Formula for area of a triangle =\frac{1}{2} \times b \times h21×b×hWhere b is base and h is height.

Formula for area of a triangle =\frac{1}{2} \times b \times h21×b×hWhere b is base and h is height.Therefore the answer is:

Formula for area of a triangle =\frac{1}{2} \times b \times h21×b×hWhere b is base and h is height.Therefore the answer is:\frac{1}{2} \times 0.075m \times 0.04m21×0.075m×0.04m

Answer 2

➲ Correct Question:-

Find the area of these triangle in square meters :

1. Base = 10.5 cm ; Height = 6 cm
2. Base = 1.5 m ; Height = 0.8 m

➲ Answer:-

★ Given:

• Base of Triangle ¹ = 10.5 cm = 0.105 m

• Height of Triangle ¹ = 6 cm = 0.06 m

• Base of Triangle ² = 1.5m

• Height of Triangle ² = 0.8 m

★ To Find:

• Area of Triangle ¹

• Area of Triangle ²

★ Formula Used:

• Area of triangle = ½ × Base × Height

★ Solution:

➢ Finding area of triangle ¹

Area of Triangle ¹

= ½ × Base × Height

= ½ × 0.105 × 0.06

= ½ × 0.0063

= 0.0063 ÷ 2

= 0.00315 m²

∴ Area of triangle ¹ = 0.00315 m²

➢ Finding area of triangle ²

Area of Triangle ²

= ½ × Base × Height

= ½ × 1.5 × 0.8

= ½ × 1.2

= 1.2 ÷ 2

= 0.6 m²

∴ Area of triangle ² = 0.6 m²

Hence,

▪︎Area of triangle ¹ = 0.00315 m²

▪︎ Area of triangle ² = 0.6 m²
