To find: The perimeter and area of the given
Answer to Problem 4PT
The perimeter and area of the triangle are
Explanation of Solution
Given information:
The figure of a triangle with dimensions is given as follows:
Figure (1)
Formula used:
(i) Pythagoras theorem for right
(ii) Area of the triangle is
(iii) Perimeter of the triangle is
Calculation:
Compute the area of the required triangle whose base
Thus, the area of the required triangle is
Use the Pythagoras theorem to compute the value of the side c.
Now, compute the perimeter of the required triangle whose sides are
Round off the perimeter value to the nearest tenth, then
Thus, the perimeter of the triangle is
Therefore, the perimeter and the area of the triangle are
