#a

  • H=10-6=4in

Area:-

[tex]\\ \sf\longmapsto \dfrac{a+b}{2}h[/tex]

[tex]\\ \sf\longmapsto \dfrac{10+6}{2}(4)[/tex]

[tex]\\ \sf\longmapsto 16(2)=32in^2[/tex]

#2

USING PYTHAGOREAN THEOREM

[tex]\\ \sf\longmapsto B^2=8.5^2-7.5^2[/tex]

[tex]\\ \sf\longmapsto B^2=72.25-56.25[/tex]

[tex]\\ \sf\longmapsto B^2=16[/tex]

[tex]\\ \sf\longmapsto B=4[/tex]

Area

[tex]\\ \sf\longmapsto LB[/tex]

[tex]\\ \sf\longmapsto 7.5(4)[/tex]

[tex]\\ \sf\longmapsto 30in^2[/tex]
