Area of A = a 2 = 20m × 20m = 400m 2 Part B is a triangle. Viewed sideways it has a base of 20m and a height of 14m. Area of B = ½b × h = ½ × 20m × 14m = 140m 2 So the total area is: Area = Area of A + Area of B Area = 400m 2 + 140m 2

And it has an option to search some things so you can search faster, it explains fully on how to do any question, thanks for making this I RECOMMEND THIS APP FOR THOSE WHO HAS A WEAK BRAIN FOR MATH LIKE ME. I use it to learn about concepts I don't understand. Great, I aced Math.

Explanations are well written and helpful, i'm doing statistics in 7th grade at the moment so obviously it's going to be a lil difficult. I am still recovering from the overwhelm.
Multiplying with area model: 16 x 27 (video)
What is Area Model? In mathematics, an area model is a rectangular diagram or model used for multiplication and division problems, in which the factors or the quotient and divisor define the length and width of the rectangle. We can break
