my answer for that question is 330 cm2 because i drew guide lines and moved some stuff and i got 5 of the thinner rectangles , so since 165cm2 is the total area ... one thin rectangle is 33 cm2 and since they want the area of the entire figure ( consists of 10 thin rectangles ) , i did 33x10 which is 330 cm2

i got 300;
3u+2p=165cm2
5u=4p
2.5u=2p
3u+2.5u=5.5u
5.5u=165cm2
1u=30
30x10=300 (x10 because 4p=5u and 5u+5u is 10u)

i might be wrong :\"\"

Don’t worry; even if u know u get the question wrong, they might give u method marks

hmm that’s possible , i don’t rmb much details of the question so could you clarify on why 5 u = 4 p ?

3u+2p=165cm. Your answer is correct
5u=4p
2.5u=2p
3u+2.5u=5.5u
5.5u=165cm
1u=30
30x10=300 (x10 because 4p=5u and 5u+5u is 10u)
