Question The length of plot is 8 meters more than its breath. If its perimeter is 80 metres, find its length and breath.

Answer: length = 24 metersbreadth = 16 meters Step-by-step explanation: Let L be length and B be breadth From the first fact we get the equationL = B + 8 (1) We know that perimeter = 2(L+B) and this is given as 80 So 2(L+B) = 80 L + B = 80/2 = 40orL = 40 – B (2) If we add equations (1) and (2) we can eliminate B We get 2L = B + 8 + 40 – B =48 L = 48/2 = 24 Substituting for L in equation (1) we get 24 = B + 8 ==> B = 24-8 =16 Cross-check Perimeter = 2 (L+B) = 2(24 + 16) = 2(40) = 80 Hence check OK Reply

Answer:24metersbreadth =

16metersStep-by-step explanation:L = B + 8 (1)

or

L = 40 – B (2)

2424 = B + 8 ==>
