Question

The length and breadth of rectangle are in the ratio 3:2.If the area of the rectangle is 726m2,find its perimeter​

Answer 1

Answer:

110 m

Step-by-step explanation:

let length , L = 3x

breadth , b = 2x

Area of rectangle = L x b = 726 square metre

( 3x ) ( 2x ) = 726 sq meter

6 x square = 726 sq meter

x square = 726 sq meter / 6

x square = 121 sq meter

x square = 11 square meter

x = 11 meter

length = 3x = 3 ( 11 m) = 33 m

breadth = 2x = 2 (11m) = 22 m

perimeter = 2 ( L + b)

= 2 ( 3x + 2x )

= 2 ( 33 m + 22m)

= 2 ( 55m)

= 110m

perimeter = 110 m

Answer 2

Answer:

LET THE NUMBER BE X

ʟᴇɴɢᴛʜ=3x

ʙʀᴇᴀᴅᴛʜ=2x

Area²=l×b

726=3x×2x²

726=6x²

726/6=x²

121=x²

√121=x

11=x

LENGTH=3x

=3×11=33

BREADTH=2x

=2×11=22

PERIMETER OF RECTANGLE

= 2×(L+B)

2×(33+22)

2×55

110
