Question

2 a The perimeter of a square is 48 m. The area of a rectangle is 4 m square
? less than the area of the given square. If the length of the rectangle is 14 m, find its breadth ​

Answer 1

Answer:

10m is the breadth

Step-by-step explanation:

4a = 48

a = 12

area of square = a×a =12×12=144

area of rectangle = 144-4 = 140

area of rectangle = l×b

140 = 14×b

140/14 =b

10 m =b ✅

Answer 2

Answer:

perimeter of square=48m

4×side=48

side =48/4

side=12m

area of a square = side ×side

12×12

144m2

area of rectangle =l×b

(144-4)M2

=140m2

area of rectangle= 140m2

l×b=140

14×b=140

b=140/14

b=10m

Hence breadth of a rectangle =10m
