Answer 1

The area of triangle is 55 square centimeters.

What is area?

Area is the amount of space occupied by a two-dimensional figure.

What is the formula for the area of triangle?

The formula for the area of triangle is

$Area = \frac{1}{2} \times base\times height$

According to the given question.

We have a figure of a quadrilateral which is made up of four right angled tringles.

Now,

The area of a triangle with base 5cm and height 7 cm

= $\frac{1}{2} \times 5\times 7$

$=\frac{35}{2}$

$= 17.5$ square centimeters

And, the area of triangle with base 4cm and height 5cm

= $\frac{1}{2} \times 4\times 5$

$= 10$ square centimeters

Since, the quadrilateral is made up of 2 right angled triangle with base 5cm and height 7cm and 2 right angled triangle with base 4cm and height 5cm.

Therefore, the area of quadrilateral or the given fiure

= 2( area of triangle with height 7cm and base 5cm + area of triangle with base 4cm and height 5cm )

= 2(17.5 + 10) square centimeter

= 2 × 27.5

= 55 square centimeters

Hence, the area of triangle is 55 square centimeters.
