1.	QR = 3 m, PR = 5 m, angle PQR = 90° The area of a rectangular room is 784 m2. If the length of the room is 112 m. Find its breadth.?
Answer» Let breadth of the room be bm and length of the room is l = 112 m given \(\therefore\) Area of rectangular room = lb m² But given that area of rectangular room is 784 m². \(\therefore\) lb = 784 ⇒ 112 b = 784 ⇒ b = 784/112 = 7 \(\therefore\) Breadth of the rectangular room is 7m.

Answer»

Let breadth of the room be bm and length of the room is l = 112 m given

\(\therefore\) Area of rectangular room = lb m²

But given that area of rectangular room is 784 m².

\(\therefore\) lb = 784

⇒ 112 b = 784

⇒ b = 784/112 = 7

\(\therefore\) Breadth of the rectangular room is 7m.
