Question

The perimeter of a rectangular plot is 174 m and its breadth is 35 m. Find the length
and the area of the plot.
11. A square and a rectangle have equal areas. If each side of the square is 18 cm and the
width of the rectangle is 12 cm, find the length of the rectangle.​

Answer 1

Answer:

length=52m of first question.

Answer 2

Perimeter of Rectangular Plot = 2 × (Length + Breadth)

⇒ Perimeter of Rectangular Plot = (2 × Length) + (2 × Breadth)

⇒ Perimeter of Rectangular Plot = (2 × Length) + (2 × 35 m)

⇒ Perimeter of Rectangular Plot = (2 × Length) + 70 m

⇒ 174 m = (2 × Length) + 70 m

⇒ 174 m - 70 m = (2 × Length)

⇒ 104 m = (2 × Length)

⇒ 104 m/2 = Length

⇒ Length = 52 m

Area of Rectangular Plot = Length × Breadth

⇒ Area of Rectangular Plot = 52 m × 35 m

⇒ Area of Rectangular Plot = 52 × 35 m²

⇒ Area of Rectangular Plot = 1820 m²
