Question

Find the value of m if 2 1/4 : 6 = m
m : 1 1/5
​

Answer 1

Answer:

Area = 1/2 [5(3−2m)+2(2m−1)+8(1−3)]

=1/2 [15−10m+4m−2+(−16)]

= 1/2 {15−18−6m}

= 1/2(−3−6m)=0

⇒(3+6m)=0

= m=− 1/2

Answer 2

Answer:

Area = 1/2 [5(3−2m)+2(2m−1)+8(1−3)]

=1/2 [15−10m+4m−2+(−16)]

= 1/2 {15−18−6m}

= 1/2(−3−6m)=0

⇒(3+6m)=0

= m=− 1/2
