Answer:
530 m²
Step-by-step explanation:
First of all we need to label the missing sides ,please check the figure I provided for that :
x = 37 - (10+ 15) = 37 - 25 = 12
z = 10
y = 2 × 10 = 20
The shade does area = area of the whole rectangle − the white area
= 37 × 20 − [ (15×20)÷2 + (10×12)÷2 ]
= 740 − [ 150 + 60 ]
= 740. − 210
= 530
Answer:
Number of sent mail = 36
Number of received mail = 75
Step-by-step explanation:
Let,
x be the number of mails sent
y be the number of mails received
According to given statement;
x + y = 111 Eqn 1
y = 2x + 3 Eqn 2
Putting value of y from Eqn 2 in Eqn 1
x + 2x + 3 = 111
3x = 111 - 3
3x = 108
Dividing both sides by 3
Putting x = 36 in Eqn 2
y = 2(36) + 3
y = 72 + 3 = 75
Hence,
Number of sent mail = 36
Number of received mail = 75
