Question

Find the area of PQRS if PR = 16.5 m, SA-42 m, QB = 3.8 m. Also, find
the cost of painting the picture at the rate of 25 per cm-​

Answer 1

Step-by-step explanation:

PR = 16.5

SA = 4.2

QB = 3.8

so according to the given diagram in the triangle PSR the PR is perpendicular till the point S so it is the altitude of the triangle

Now, area of PSR

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

Area = \frac{1}{2} \times 16.5 \times 4.2

Area = 34.65
