Answer:
230cm²
Step-by-step explanation:
The shape can be split into two shapes horizontally: a triangle and a rectangle.
<u>Area of the rectangle</u>
The area of a rectangle = length × width
In this case, the length is 20cm and the width is 7cm. 20 × 7 = 140cm²
<u>Area of the triangle</u>
The area of a triangle = 1/2 × base × height
In this case, the base is 20cm and the height is 9cm (16cm - 7cm). 1/2 × 20 × 9 = 90cm²
<u>Area of the shape</u>
To find the area of the total shape, we can add 140cm² and 90cm² to get 230cm².
Hope this helps!
Answer:
RS = 10
Step-by-step explanation:
We are told that to get ∆QRS, the scale factor of ⅖ was used. To get side RS, we would multiply the side length of the side that corresponds to RS.
YZ corresponds to RS.
YZ = 25
Thus,
RS = 25*⅖
RS = 10
Answer:
5x+17
Step-by-step explanation:
2(x+7)+3(x+1)
=2x+14+3x+3 you remove the bracket
=2x+3x+14+3 you collect like terms
=5x+17
100 is 10 times 10,
