Example:

The below-solved example problem may be useful to understand how the values are being used in the mathematical formulas to find the trapezoid area.

Example Problem :

Find the area of a trapezoid having the bottom length a = 15 cm, top length b = 12 & height h = 9 cm?

Solution :

The given values

bottom length a = 15 cm

top length b = 12 cm

height h = 10 cm

Step by step calculation

formula to find area = ((a + b)/2) h

substitute the values

= ((15 + 12)/2) x 9

= 121.5 cm2

Four glasses of milk and 2 snack bars have a total of 72 carbohydrates (carbs), and 2 glasses of milk and 3 snack bars have a t

Travka [436]

One glass of milk has 11 carbs and one snack bar has 14 carbs.

Step-by-step explanation:

Let,

Glass of milk = x

Snack bar = y

According to given statement;

4x+2y=72 Eqn 1

2x+3y=64 Eqn 2

Multiplying Eqn 2 by 2

$2(2x+3y=64)\\4x+6y=128\ \ \ Eqn\ 3$

Subtracting Eqn 1 from Eqn 3

$(4x+6y)-(4x+2y)=128-72\\4x+6y-4x-2y=56\\4y=56$

Dividing both sides by 4

$\frac{4y}{4}=\frac{56}{4}\\y=14$

Putting y=14 in Eqn 1

$4x+2(14)=72\\4x+28=72\\4x=72-28\\4x=44$

Dividing both sides by 4

$\frac{4x}{4}=\frac{44}{4}\\x=11$

One glass of milk has 11 carbs and one snack bar has 14 carbs.
