Area Of Rectangle
= 2 length × 2 width
= 2 l + 2 w
l = 2 w -3................equation (i)
2 l + 2 w = 42..........equation (ii)
2(2 w -3) + 2 w =42
4 w - 6 + 2 w = 42
4 w + 2 w = 42 + 6
6 w = 48
w =8
l = 2 w - 3
l = 2×8 - 3
l = 13
Length = 13
Width = 8
Answer:
De value of k is 9
Step-by-step explanation:
6,-1
b(1,3)
(k,8)
am using bodmas
a6-1×1=6a
b1×3=3b
abc=8
6a+3b+8=17-8
=9
16 is the answer. I can explain if you need
Answer:
question 1 , area= 42.02 sq meter, circumference=22.98 meter
question 2, area=481.609sq meter, lenght of BC=263.3472 meter
for convience i converted yards to meter.
Step-by-step explanation:
in first question to find area of circle by multiplying value of pi (3.14) and square of radius of circle and to find circumference just multiply 2 with value of pi(3.14) and radius of circle.
in the second question to find area of sector use formula 1/2 r^2 x72 and to find lenght of arc bc use formula length= radius x 72
the greatest common factor is 2
