Question

what is the length of a rectangle whose perimeter and breadth are equal to 270 cm and 45 cm respectively​

Answer 1

Answer:

perimeter=270cm breadth=45cm

270 = 2(l+b)

270 = 2(l+45)

270/2 = l+45

135 = l+45

l=135-45

l=90

Step-by-step explanation:

equate perimeter to the formula

Answer 2

Answer:

Given breadth of a rectangle =45cm

perimeter of a rectangle. =270cm

2(l+b). =270cm

2(l+45). =270cm

l+45. =270/2

l. = 135-45

l. = 90cm

#therefore the length of a rectangle is 90 cm
