Question

The wall around a playground measure 410m. If one wall along the length of the playground is 80 m long,what is the area of the playground

Answer 1

Answer:

 i think the answer is 328

Answer 2

$p = 410m \\ l = 80m \\ therefore \: b = ( \div 2410 - 2(80)) \\ = (410 - 160) \div 2 = 250 \div 2 \\ = 125m \\ area = l \times b \\ = 80 \times 125 \\ = 10000 {m}^{2}$
