Answer:
3 times 4 + 5 = 17
Step-by-step explanation:
3d+5=17
-5 -5
________
3d = 12
__ __
3 3
d = 4
Answer:
1st question is 1:2
2nd question is 5
Step-by-step explanation:
15 times two is 30, so if you divide both 15 and 30 by 15, you get 1:2
Divide 300 and 60 and you get 5.
If perimeter is 60 so the side is 60 ÷ 3 = 20
Now we can apply the area formula for triangles;
Answer: 42.5 m
Step-by-step explanation:
Split the figure into a rectangle and a triangle.
Find the areas of the rectangle and the triangle seperately and add them together.
Rectangle: 7 x 5 = 35
Triangle: 5 x 3/2 = 7.5
35+7.5= 42.5m
