I need help with these two questions

Given

Step-by-step explanation:

The Lateral surface area is the surface area of only 4 sides of the figure, that is, area excluding top and bottoms sides.

Lateral surface area of cuboid

= 2h (l+b)

where h is height

b is breadth

l is length

= 2*12 (5+4)

= 2*12*9

= 216 m^2

Lateral surface area of cube

= 4s^2

where s is the side

= 4*(2)^2

= 4*4

= 16m^2

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )
