Question

find the area of rectangular garden whose length is twice the breadth and perimeter is 60 cm ....
​

Answer 1

Answer:

200cm²

Step-by-step explanation:

LENGTH = 20cm

BREADTH = 10cm

AREA = 200cm²

Step-by-step explanation:

PARAMETERS GIVEN,

PERIMETER = 60cm

LET THE BREADTH BE x

SO,

LENGTH = 2x

SO,

PERIMETER = 2(LENGTH + BREADTH)

60cm=2(2x+x)

60cm=2*3x

60cm=6x

x=60cm/6

x=10cm

2x=20cm

SO,

AREA OF THE RECTANGLE = LENGTH * BREADTH

                                              = 20cm*10cm

                                              = 200cm²
