Care fully look ok = 3(3m - 5) - 4(4m-2) = 9m - 15 - 16m + 8 ( in this step we multiplied 3 and 3m, 3 and 5, 4 and 4m, 4 and 2, as u know if we multiply two negative numbers the result will be positive) = 16m - 9m - 15 + 8 ( in this step we took like terms and wrote them sequencely) = 7m - 7 ( answer ) (in this step we have to add and subtract , got it ) Hope it will help u

Anas Saifi 6 years, 1 month ago

36 cm= 0.36 m and 10 cm=0.1m area of parallelogram = base ×height 0.36×0.1= 0.036m^2 now we have to divide 1440m^2 by 0.036m^2 after dividing we get 40000 thus, 40000 tiles are needed
