Answer:
1 hour 54 minutes
Step-by-step explanation:
1 hour and 9 minutes + 45 minutes gives your answer. However, since 45+9=54, this is convenient, since now we don't need to carry. Thus, 1 hour and 54 min is your answer.
Hope this helps!
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!
Width = W
Length = 3 times w = 3W
Area = length x width = 3W * W = 3W^2
X=17
Angle E= 155°
Angle G=57°
Angle H=58°
