Question

area of a square field is 5184 m2. A rectangular field, whose length is twice its

breadth, has its perimeter equal to the perimeter of the square field. Find the area

of the rectangular field.

8. Find the value of 47089 + 24336​

Answer 1

Step-by-step explanation:

Area of Square field = 5184 m²

a² = (72)²

a = 72 m

For Rectangular field ,

breadth = x , length = 2x

Square & rectangle have same perimeter . perimeter of square field = 4a = 4×72 = 288 m

perimeter of rectangular field = 2 × ( L + b )

288 = 2 × ( 2x + x )

144 = 3x

x = 144/3 = 48 m

length = 2(48) = 96 m

breadth = 48 m

Area of the rectangular field = length × breadth

= 96 × 48

= 2×48×48

= 2 × 2304

= 4608 m²

Q.(8) 47,089 + 24,336

= 71,425
