Question

the perameter is rectangle is 249m,if the length is 85 m.find the area in arcs​

Answer 1

Answer:

perameter = 249m

l = 85

peri => 2(l+b)= 2(85+b)=249

=> b= (249-170)/2

=> b = 39.5

area => lb = 85x39.5=3357.5m = 0.8296 acres

Answer 2

Answer:

0.8296563183 ACRES!!!

Step-by-step explanation:

PARAMETERS GIVEN,

PERIMETER OF THE RECTANGLE = 249m

LENGTH = 85m

LET THE BREADTH BE x

SO,

A.T.Q.,

PERIMETER = 2(LENGTH+BREADTH)

249=2(85+x)

249=170+2x

2x=249 - 170

2x = 79

x=79/2

x= 39.5m

NOW,

AREA = LENGTH*BREADTH

          = 85m*39.5m

          = 3357.5m²

NOW,

CONVERTING IT INTO ACRES WE GET,

3357.5m² INTO ACRES

0.8296563183 ACRES
