# There is a slide in a park. One of its side walls has been painted in some color with a message “KEEP THE PARK GREEN AND CLEAN.” If the sides of the wall are 15 m, 11 m, and 6 m, find the area painted in color.

Given: Sides of the walls are 15 m, 11 m, and 6 m.

To Find: Area painted in color.

Concept Used:

If sides of a triangle are a, b, and c, then area of a triangle is given by:

Where s = semiperimeter of the triangle

Assumption:

Let the sides of the triangle be,

a = 15 m

b = 11 m

c = 6 m

Explanation:

s = 16 m

Area = 20√2 m2.

Hence, the area of wall painted in color is 20√2 m2.
