find the area of figure 2,as per dimensions given in it.
Answers
Answer:
Answer:
47 units^2
Step-by-step explanation:
∵ THE TRIANGLES ARE RIGHT ANGLED TRIANGLES
∴ BY PYTHAGORAS THEOREM,
5^2 = 3^2 + BASE^2
⇒ BASE = 4 units
AREA OF 2 TRIANGLES (BOTH HAVE THE SAME DIMENSIONS) = 2*1/2*H*B
= 3*4
= 12 unit^2
AREA OF RECTANGLE = L*B
= 5*(3+4)
= 5*7
= 35 units^2
AREA OF FIGURE = 35 + 12 = 47 units^2
