\(Area \;of\; parallelogram = Base \times Height\)
(a)\( Height= 4 \;cm\)
\(Base = 7\; cm\)
\(Area\; of \;parallelogram = 7 \times 4 = 28 \;cm^2\)
(b) \(Height= 3 \;cm\)
\(Base = 5 \;cm\)
\(Area \;of \;parallelogram = 5 \times 3 = 15 \;cm^2\)
(c) \(Height= 3.5 \;cm\)
\(Base = 2.5 \;cm\)
\(Area\; of\; parallelogram = 2.5 \times 3.5 = 8.75 \;cm^2\)
(d) \(Height= 4.8 \;cm\)
\(Base = 5 \;cm\)
\(Area\; of\; parallelogram = 5 \times 4.8 = 24 \;cm^2\)
(e) \(Height= 4.4 \;cm\)
\(Base = 2 \;cm\)
\(Area\; of\; parallelogram = 2 \times 4.4 = 8.8 \;cm^2\)
Write equations for the following statements:
(i) The sum of numbers x and 4 is 9.
(ii) 2 subtracted from y is 8.
(iii) Ten times a is 70.
(iv) The number b divided by 5 gives 6.
(v) Three-fourth of t is 15.
(vi) Seven times m plus 7 gets you 77.
(vii) One-fourth of a number x minus 4 gives 4.
(viii) If you take away 6 from 6 times y, you get 60.
(ix) If you add 3 to one-third of z, you get 30
