Given:

↪Two sides of the ||gm ABCD are 6cm and 4cm.

↪The height of corresponding of the base CD is 3cm.

To Find:

i) Area of ||gm

ii) Height of the corresponding to the base AD

Solution:

[Refer the attached figure for ||gm ABCD]

AB = CD = 6cm

BC = AD = 4cm

Height, AE = 3cm

i) Area of ||gm = base × Height

= 3 × 4

= 12cm²

Hence, Area of ||gm is 12m²

ii) In ∆ADF

AE = FD = 3cm

AD = 4cm

By Pythagoras Theorem

(AF)² = (AD)² - (FD)²

= (4)² - (3)²

= 16 - 9

= 7

(AF)² = 7

AF = √7cm

Hence, the height of the corresponding to the base AD is √7cm.

AB = CD = 6cm

BC = AD = 4cm

Height, AE = 3cm

i) Area of ||gm = base × Height

\implies 3 × 4

\implies 12cm²

Hence, Area of ||gm is 12m²

ii) In ∆ADF

\impliesAE = FD = 3cm

\impliesAD = 4cm

By Pythagoras Theorem

(AF)² = (AD)² - (FD)²

\implies (4)² - (3)²

\implies 16 - 9

\implies 7

\implies(AF)² = 7

\impliesAF = √7cm

Hence, the height of the corresponding to the base AD is √7cm.
