The formula below is used to calculate the area of a trapezium.
• a and b represent the length of the two parallel sides.
• h represents the height of the trapezium
Calculate the area of the trapezium at right using the formula below.

14 cm^2

Step-by-step explanation:

from the data given ,

A = 3 cm

B = 5 cm

H = 4

according to the given formula  ,

Area = H / 2 ( A + B )

Substituting values ,

Area = 4/2 * ( 3 + 4 )

Area = 4/2 * ( 7)

Area = 28 / 2

Area = 14

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
