Question

A verandah 2 m wide is constructed all around outside a room of size 8 m by 5 m . Find the area of the verandah .​

Answer 1

Step-by-step explanation:

In a parallelogram, opposite angles are equal.

Since ∠A=70o=∠C=65o

Hence quadrilateral ABCD is not a parallelogram

Area of room=AB×BC=8m×5m=40m2

Area of room along with verandah=area of the rectangle PQRS=QR×RS=9m×12m=108m2

∴ Area of verandah=Area of rectangle PQRS−area of rectangle ABCD=108om2−40m2=68m2.
