i) Area = length x width
=250 x 100
= 25000 cm2
ii) it is a square so the sides are equal
Area = 10 x 10
= 100cm2
iii) 25000/100
250 tiles will be needed
Iv) one tile is 4.75 dollars
Total tiles are 250
Cost for tiling
=250 x 4.75
=1187.5
Hope this helps
D.) 7(8 - X) - 5 = 40
let X = unknown number
eigth minus a number is 8 - x. since the product is seven and eight minus a number then 7 * [8-x] or 7(8-5).
40 is its equivalent when the product is decreased by 5; therefore, 7(8-x) - 5 = 40.
