Help me with 12 and 13 pls

Step-by-step explanation:

12)  Solution,

For small quadrilateral

Length(l)=3in

Breadth(b)=1in

Area=lxb=3x1=3in²

For big quadrilateral

Base(b)=5in

Height(h)=5in

Area=bxh=5inx5in=25in²

Area of Shaded part=25in²-3in²=22in²

13)Solution,

Length =2cm

Breadth=0.5 cm

Area=2cmx0.5cm=1cm²

Base=4cm

Height=2cm

Area=bxh=4cmx2cm=8cm²

Area of shaded part=8cm²-1cm²=7cm²

the answer is 37

step-by-step explanation:

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2

happy to
