Chapter 1.6, Problem 8CYU

To determine

To calculate area and perimeter.

Answer to Problem 8CYU

  Perimeter is 30m.

  Area of triangle is 60 meter square

Explanation of Solution

Given information:

  

Formula used:

  Perimeter of triangle is,

  $perimeter=sumOfAllSides$

  Area of triangle,

  $area=\frac{1}{2}bh$

Calculation:

For the perimeter, substituting the values,

  $perimeter=15+8+17$

On solving,

  $perimeter=30$

Hence, perimeter is 30m.

For the area, substituting the value,

  $area=\frac{1}{2}\times 15\times 8$

On solving,

  $area=60$

Hence, area of triangle is 60 meter square
