sir i want to ask you something that makes confuse me.that is what if i sub struct the larger nu from the smaller nu and multiply it to find the area like this (9-7)(15-6)
They have to give you enough information to find its Area. If it's a square, one measurement (side length) would be enough. If it's a circle, one measurement (radius OR diameter) would be enough,.
When a diagram in a Math question looks like one shape but has labels that tell you it is another shape, believe the labels and work with them. We Math teachers often draw diagrams incorrectly on purpose, so that trying to solve with rulers and such tools won't work, because we know what techniques we want the students to use. (And, of course, sometimes it's just because the Math teacher made a mistake.)
