The triangle's height would have to be 2 times that of the rectangles. To know this, you canlook at the formulas for the Area of each shape.

Rectangle: bh

Triangle: bh/2

A triangle is just a rectangle cut in half. In order for the areas to be the same asleep as the bases, the only way it can be true is if the height were 2 times larger than the height of the rectangle.

nata0808 [166]

Answer:

here I'm confused that whether the selling price is Rs.9,200 or Rs.9.200

any ways you can take the help of below procedure

Step-by-step explanation:

here,

let marked price be X

discount(d)=20%

VAT=15%

SP with VAT= 9200

now,

SP without VAT= SP - VAT of SP

= 9200-15/100 ×9200

= 9200- 1380

=Rs. 1380

again,

SP= MP - D of MP

or,7820= x- 20/100 × x

or, 7820× 100 = 100x- 20x

or,782000=80x

or, 782000/80=X

or, X= 9775.

hence MP is Rs 9775

LuckyWell [14K]

Answer:

58 miles per hour

Step-by-step explanation:

First you need to divide 80 by 10 to see how many miles she was over the speed limit.

80/10 = 8 miles over the speed limit.

The speed limit was 50, so 50 + 8 = 58 miles.

So Cathy was driving at 58 miles per hour
