The area of a rectangular swimming pool is 35m² while the perimeter is 24cm. find the length of the swimming pool

5 or 7 metres

Step-by-step explanation:

{24 = 2w + 2l

{35 = wl

Setting it up like this, plugging 5 and 7 into both equations for w and l will not alter a thing. You will still get the exact same result, no matter the possible outcomes.

By the way, I think you meant 24 m, not cm..

I am joyous to assist you anytime.

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
