Question

the base of the corresponding height of a triangle are 7.5 cm and 4cm respectively.find the area of a triangle ​

Answer 1

Step-by-step explanation:

Given:-

The base of the corresponding height of a triangle are 7.5 cm and 4cm respectively.

To find:-

Find the area of a triangle ?

Solution:-

Base of the triangel (b)=7.5 cm

Height of the triangle(h)=4 cm

Area of the triangle =bh/2 sq.units

=>Area of the triangle

=(7.5×4)/2

=>7.5×2

=>15 cm²

Answer:-

Area of the given triangle =15 sq.cm

Used formula:-

• Area of the triangle whose base "b" units and height of the triangle "h" units is bh/2 sq.units.
• Area of the triangle is equal to the half of the product of its base and the corresponding height.

Answer:-

Answer 2

Correct Question:-

The base and the corresponding height of a triangle are 7.5 cm and 4cm respectively. Find the area of a triangle.

Answer:-

Given:

• Base of triangle = 7.5 cm

• Height of triangle = 4cm

To Find:

• Area of triangle

Solution:

Area of triangle

= ½ × Base × Height

= ½ × 7.5 × 4

= 7.5 × 2

= 15 cm²

∴ Area of triangle is 15 cm².

Formula to be remembered:-

▪︎Area of square = Side × Side

▪︎Area of rectangle = length × breadth

▪︎Area of parallelogram = Base × Height

▪︎Area of Rhombus = ½ × d¹ × d²

▪︎Area of triangle = ½ × Base × Height

Or

by Heron's Formula.
