Answer:
398 ft²
Step-by-step explanation:
Assuming you have correctly described the total area in terms of non-overlapping triangles and a rectangle, you can put the dimensions into the appropriate area formula and add up the pieces.
Triangle area = 1/2·bh
Rectangle area = bh
___
So, the <em>first triangle</em> has an area of ...
1/2·(20 ft)(20 ft) = 200 ft²
The <em>second triangle</em> has an area of ...
1/2·(6 ft)(6 ft) = 18 ft²
The <em>rectangle</em> has an area of ...
(30 ft)(6 ft) = 180 ft²
And the area total is ...
200 ft² +18 ft² +180 ft² = 398 ft²

Answer:
Total = $49.05
Step-by-step explanation:
cost of grapes per pound = $ 2.50
she bought 3 pounds of grapes
so cost of 3 pounds of grapes = 3 × 2.50
= 7.5
gallon of milk = 8.6 pound
so cost of 8.6 pound of milk = 8.6 × 4.25
= $36.55
$ 1.50 off means =$4 - $ 1.50 = $2.5
cost of 2 boxes of cereal = 2 × 2.5
= $ 5
Total = 7.5 + 36.55 + 5
Total = $49.05
