To find the area of a rectangle, you multiply the base by the height.
So in this case, the base of the rectangle would be 17cm, and the height would be 22.
17 x 22 = 374cm²
You also need to find the area of the triangle.
The area of a triangle is the base multiplied by the height and then halved.
In this case, the base would be 19cm, and the height would be 22 - 10 = 12 (if you minus 10 from 22, you would find the length of the unknown side of the triangle).
19 x 12 = 228
Half of 228 is 114cm²
Add the area of the triangle with the area of the rectangle to give the area of the whole shape.
374 + 114 = 488cm²
The scale factor is 0.25, not 4 in this case. You can determine this by looking at the comparison of the triangles. The first triangle is 4.4 and the second one is 1.1, so the scale factor is determined by looking at what is happening to the first one to result in the second.
0.25 is 1/4. The second hypotenuse is 1/4 the hypotenuse of the first one.
Yes 0.007*10= 0.07
Youre correct
57 / 60 will give you the percentage! :)
